Johnsongrass (also called grass sorghum, egyptian millet) is a perennial species over most of its range. Leaves are grasslike, up to 1" wide, with a prominent whitish midvein. The ligule is short and membranous with a hairy fringe; auricles are lacking. Stems can grow up to 8' in height, but our annual specimens will be closer to 3' — 4' tall. Large, open panicles are up to 1' long and emerge in midsummer. Spikelets are reddish in color and most are tipped by bent awns. Scaly, finger-thick rhizomes are produced from the crown.
